CE ÎNSEAMNĂ WINGLET ÎN ENGLEZĂ?
Dispozitiv Wingtip
Dispozitivele Wingtip sunt de obicei destinate îmbunătățirii eficienței aeronavelor cu aripă fixă. Există mai multe tipuri de dispozitive cu aripi și, deși funcționează în moduri diferite, efectul urmărit este întotdeauna reducerea rezistenței aeronavei prin recuperarea parțială a energiei vârtejului de vârtej. Dispozitivele Wingtip pot îmbunătăți caracteristicile de manipulare a aeronavelor și pot spori siguranța pentru următoarele aeronave. Astfel de dispozitive măresc raportul efectiv de aspect al unei aripi fără a mări semnificativ anvergura aripilor. O prelungire a intervalului ar reduce dragul indus de ridicare, dar ar crește rezistența parazitară și ar necesita creșterea rezistenței și greutății aripii. La un moment dat, nu există nici un beneficiu net din creșterea sporită. De asemenea, pot exista considerații operaționale care limitează aripile admise. Dispozitivele Wingtip sporesc liftul generat la vârful aripii și reduc tracțiunea indusă de ridicare provocată de vârtejurile tip wingtop, îmbunătățind raportul lift-tragere. Aceasta sporește eficiența consumului de combustibil în aeronavele cu motor și crește viteza de deplasare în aerodinamică, în ambele cazuri crescând intervalul. S.U.A.
Definiția winglet în dicționarul Engleză
Definiția winglet-ului în dicționar este o aripă mică, mai ales aripă bastardă a unei păsări. O altă definiție a winglet-ului este o mică aripă așezată la vârful aripii principale a unei aeronave și perpendiculară pe aceasta, concepută pentru a reduce dragul vortexului aeronavei.

For lower lift values (cL < 0.3 RANS and cL < 0.2 ETW), the winglet case
generates more drag than the reference configuration. This results from
additional skin friction produced by the winglet. At higher lift coefficient the large
